The last update on his condition was posted two weeks ago, when Jim Summerill of Washington DC wrote on the police department’s Facebook page that his son was “still unconscious and being transported to level one trauma center.”

NOAA lightning expert John Jensenius sent out a press release Wednesday saying the death marked the nation’s 16th lightning fatality this year. “Prior to this fatality, the most recent fatal incident in North Carolina occurred on July 28, 2018, when a man was struck and killed in Raleigh while walking through an auto salvage yard,” Jensenius said.

“He was in the water near shore, throwing a Frisbee with two friends, when a lightning bolt came out of the clear blue sky and struck him in the lower back. His two friends collected themselves and realized Matthew was face down in the water,” according to the GoFundMe page.

“They took him to shore and started performing CPR, and the lifeguard rushed an oxygen tank to him right away. Medical services took over soon after...”

Summerill had been “in a medically induced coma” at a Greenville hospital since the incident, the campaign page said.
